1. The problem statement, all variables and given/known data Give the IUPAC name of the following compound ＯＨ Cl ｜ ｜ Ｃ－Ｃ－Ｃ－Ｃ ｜ ＯＨ (Noteydrogen atoms are not drawn) 2. Relevant equations 3. The attempt at a solution Model answer:3-chlorobutane-1,2-diol Why it is called 3-chlorobutane-1,2-diol instead of 3-chlorobutan-1,2-diol? Consider CH3CH2CH2OH,it is propan-2-ol,where "e" from "propane" is dropped. So e from 3-chlorobutane-1,2-diol should also be deleted?
